1.write down the difference between scanner and digital camera ?
2. write down some units of data storage?
3. what is a Ram ? explain

Answer:
Digital camera is portable and can capture any real life image, it a true 3D effect and feel. A scanner is limited to flat 2D previously captured and rendered images purely to dump them into a digital format.
Computer data is expressed as bytes, kilobytes, megabytes as it is in the metric system, but 1 kilobyte is 1024 bytes not 1000 bytes. Data storage units are: bit (b), byte (B), kilobyte (KB), megabyte (MB), gigabyte (GB), terabyte (TB), petabyte (PB), exabyte (EB), zettabyte (ZB) and yottabyte (YB).
RAM (pronounced ramm) is an acronym for random access memory, a type of computer memory that can be accessed randomly; that is, any byte of memory can be accessed without touching the preceding bytes. RAM is found in servers, PCs, tablets, smartphones and other devices, such as printers.
" A Digital camera is portable and can capture any real life image, it a true 3D effect and feel. A scanner is limited to flat 2D previously captured and rendered images purely to dump them into a digital format. The single advantage that a scanner has over a Digital camera is the ability to capture a near true copy of the original that can be used to create accurate identical copies."
Now we could start looking a little deeper into it..
"A scanner has a fixed focal point and cannot accuratly aquire 3D objects or items that are not placed directly on the fixed focal plane (ie. the scan glass). Where as a digital camera has a variable focal point that can within reasonable accuracy capture any 3D oject."
